The EL3002 analog input terminal processes signals in the range between -10 and +10 V. The voltage is digitized to a resolution of 12 bits, and is transmitted, electrically isolated, to the higher-level automation device. The input channels of the EtherCAT Terminal are single-ended inputs with a common, internal ground potential. The signal state of the EtherCAT Terminals is indicated by light emitting diodes.
The EL3174-0002 analog input terminal has four individually parameterizable inputs. Signals in the range from -10/0 to +10 V or -20/0/+4 to +20 mA can be processed via each channel. Each channel should be set by the controller to U or I mode via CoE.
The EL3201-0020 is the factory calibrated version of the EL3201-0010. The EL3201-0020 analog input terminal facilitates the direct connection of a resistance sensor. The measured resistance value can either be output directly in ohms or transformed into a temperature.
The EL3202-0020 is the factory calibrated version of the EL3202-0010. The EL3202-0020 analog input terminal facilitates the direct connection of two resistance sensors. The measured resistance value can either be output directly in ohms or transformed into a temperature.
The EL3314-0020 analog input terminal allows four thermocouples to be connected directly. The EtherCAT Terminal circuit can operate thermocouple sensors using the 2-wire technique. A microprocessor handles linearization across the whole temperature range, which is freely selectable. The error LEDs indicate a broken wire. Compensation for the cold junction is made through an internal high-precision temperature measurement at the terminal.
The analog EL3356-0020 input terminal enables direct connection of a resistor bridge or load cell in a 4- or 6-wire connection technology. The ratio between the bridge voltage UD and the supply voltage UREF is determined simultaneously in the input circuit and the final load value is calculated as a process value on the basis of the settings in the terminal.
he 2-channel analog input terminal EL3602-0002 is a variant of the EL3602 for measurements in the range ±200 mV. The voltage is digitized to a resolution of 24 bits, and is transmitted, electrically isolated, to the higher-level automation device.
The EL3602-0020 analog input terminal handles signals in the ranges ±10 V, ±5 V, ±2.5 V and ±1.25 V. The voltage is digitized to a resolution of 24 bits, and is transmitted, electrically isolated, to the higher-level automation device.
